I am getting the same error. There has to be something up with this, its too strange... Also, making the parameter an array did not fix it. Also, it DID work 1-2 times, but at multiple tries it fails with 400.

Hi, I'm new to clarifai. Copied the sample for Node, works great if the photo is located on https://samples.clarifai.com domain. If I use photos on my own server and base64 strings, all seem to be failed with errors below. Any advice is much appreciated.
